- Develop a metal activity series
- Build a wet cell battery to power an electrical device
- Investigate variables that affect battery performance
Grades 9–12. Students discover how metals can vary in chemical activity and use this knowledge to test combinations of metals to produce voltaic cells. They use the cell with the highest voltage output to power various electrical devices and an electrolytic cell for extracting elements and plating metals. Finally, students design experiments to investigate variables that could affect the voltage and amperage of their voltaic cell.
Part of the Inquiries in Science™ series. Materials are sufficient for 30 students working in groups of 3.
